What I have:
What I need is :
How to arrive for both combined..
Any help is much appreciated
- A hollow cylinder filled 1/3 its dia with slurry.
- Wt of cylinder is 987251 pounds
- Wt of slurry is 358157 pounds
- Radius of cylinder = 8.5 ft.
- RPM = 7.5
- Time taken = 20 seconds
What I need is :
- Torque required to roate the cylinder
- Torque required to rotate the slurry inside along with the cylinder
- Mass = Wt / accn due to gravity = 987251 / 32.2 = 30659.9 (where accn.due to gravity is in ft/sec^2)
- Torque required to rotate cylinder is Tcyl= (30659.9 * 8.5^2 * 2* Pi*RPM)/(60*20)
How to arrive for both combined..
- Is it the same procedure too? That is calculate torque reqd for the slurry too and then add both ?
Instead, can we use Torque = Force*Radius principle to arrive at the Torque required for rotating the slurry - How to calculate the start up torque
- Remember having learned some perpendicular axes theorem or parallel axes thoerom., do those apply ?
Any other method towards solving this ??
Any help is much appreciated
